I offer for sale a pair of vintage step-up Moving Coil Phono input transformers from famous German manufacture Lorenz AG - type 31H37 produced in end of 40s. These transformers are in a very good condition according of the age, and work perfect. They are highly wanted, as so called big housing step-up input transformers. The dimension of the MU-Metal cans is: - 57 mm the diameter, and the height is about 60 mm including the fixing stripe. These transformers are perfect suitable as MC step-up input transformers for all phono pre-amplifiers with MM input. The DC - input resistance is 30 Ohm, and the DC - output resistance is 3 kOhm. The ratio is 1:30 with open output, and 1:20 with a load resistance about 50 kOhm (typically MM input resistance). The frequency response is 10 Hz to 20 kHz. The frequency transmissions rate is from 10 Hz to 15 kHz +/- 0dB, and with 20 kHz they have a naturally softly abatement about -2,5 dB. These transformers are perfect applicable for MC cartridges (pick-ups) with low output impedance from 5 to 25 Ohms as for sample the Neumann DST 62, EMT-TSD 15, Ortofon SPUs or other CM-cartridges with low and high output impedance.On the photo no. 4 and 5 are showed two pairs (4 pieces), but for sale ist one pair only. The first pair has been sold already in my previously auction: https://www.ebay.de/itm/204497605246 For comparing the size of these transformers, I made a example photo together with an often offered in ebay MC Phono transformers Siemens T42/75/1 transformer (is a small dwarf only), which is not matter of this auction. Regarding the frequency response please check the last photo. This is an oscilloscope screen photo - result of a special test with 1 kHz square signal for view of the frequency response spectrum (this test method is to understanding from professional technicians only) Below is the schematic diagram for these transformers: Shipping world wide as full insured DHL/German Post packet, takes about 2-4 weeks - cost about 46 EUR respectively a shipping world wide by DHL Express as a little parcel to 1 kg - costs 65 EUR with low insurance to 50 EUR liability, or 75 EUR with full insurance. Do not hesitate to send questions to my post box: I specialized me since many years of development, construction andassembling of audio transformers - especially for adaptation of high efficiency studio transformers as step-up input transformers for Moving Coil cartridges. I make an special adaptation of transformers in originally shape as the 408721, offered in my last auction, and also an especiallyconverting of audio transformers for enhancing the transmissions rate and increasing the ratios. I accept fully liability for all what I write and offer for sale. I accept return of goods with fully money back in case a disappointment. I sold already many step-up input transformers for Moving Coils systems and never received any return. Please check my feedback. I have in preparation several new projectsactually (check below photos), on base of Rohde & Schwarz, Siemens/Klangfilm/WSW (Klangfilm Austria), Malotki/Danner and other studio vintage transformers. Please check for example some old auctions from me in last 10 years.The Rohde & Schwarz transformers from the series 4087xxx are veryheavy to find. I not found since many years, and now I found one pair,which I sold already in July 2022. The last transformers from the series4087xxx I sold in year 2014 (auction links are is below attached).Some auctions are still to find in eBay with my previously eBay ID: ampliserv - this account timely no active for sale offers Please click here for check my diverse old auctions for MC Phonostep-up input transformers (after opening you must click additionalthe superscription - See full item description): 204056198126 181551689096 181478950094 181452034699 181429443512 181351849267 180796982947 170890921561 170991040206 181203208474 200923358302 171103085579

Ultra rare R15 cardridge made by Neumann-Gefell Co. around 1953. Neumann R15 historic cardridge for turntables The only information you find about this unique cardridge is if you type radiomuseum tonabnehmer r15 at googleNeumann-Gefell mentions is in their time-lineas well. No other information can be found. Founded by Georg Neumann, Microtech Gefell was originally known as Georg Neumann & Company Gefell.Gefell is the name of the town to which Georg Neumann fled from Berlin in 1943.More info can be found at the Neumann-Gefell wikipedia site.Today the name Neumann-Gefell is mainly known for their outstanding measuring microphones, tube-microphoneslike the UM57 the CMV536 and their condenser microphone capsules like the M7, M8, M9, M55k and others. I suspect that the number of existing cardridges of this typeis under 5 pieces. I never saw any other pick-up built like this.It can be a treasure for a historic cardridge and phono collectionand I also really would like to listen to the sound it produces. The R15 has not been cleaned before offering it because Ido not want to destroy anything and rather leave it in theoriginal condition. Please see the microscopic photo to judge the condition of the diamond. Shipping with higher insurance. I am experienced with international shipping and pack very well. Untested historic item sold without any guarantee or the right to return the item.
